Hutchinson's "niche" (a description of the ecological space occupied by a species) is subtly different from the "niche" as defined by Grinnell (an ecological role, that may or may not be actually filled by a species—see vacant niches). A niche is a very specific segment of ecospace occupied by a single species.
A species' realized niche is usually much narrower than its fundamental niche width as it is forced to adjust its niche around the superior competing species. The physical area where a species lives, is its habitat. The set of environmental features essential to that species' survival, is its "niche." (Ecology. Begon, Harper, Townsend)
Species distribution modelling (SDM), also known as environmental (or ecological) niche modelling (ENM), habitat modelling, predictive habitat distribution modelling, and range mapping [1] uses ecological models to predict the distribution of a species across geographic space and time using environmental data. The environmental data are most ...

This was the definition Eugene Odum popularized in his analogy of the niche of a species with its profession in the ecosystem as opposed to the habitat being its address.
